Photocatalytic degradation of MB by persulfate synergizing with CoAl2O4
The 3D hierarchical CoAl2O4 was prepared successfully by one-step the hydrothermal method.The influence for morphology,composition and physicochemical properties on photocatalytic performance was investigated by XRD,SEM and UV-Vis.The CoAl2O4/PS/Vis coupled system was constructed to remove the MB containing the wastewater.Due to the unique 3D characteristic as well as synergistic effect between CoAl2O4 and PS,the removal ratio of CoAl2O4/PS/Vis system for MB reached to 94.8％under visible irradiation 100min.The enhanced mechanism for mineralization MB of CoAl2O4/PS/Vis system was discussed detailed.
